Abstract
Currently, the Oregon Department of Transportation is investigating the potential for increasing the truck speed limit from 55 to 60 mph in segments where the current speed limit is 65 for cars/light vehicles and 55 mph for trucks. This report summarizes the literature on the operational and safety impacts of raising speed limits, the effect of uniform versus differential speed limit policies, and truck equipment and work zone policies. This report updates select topics from a previously published report “Impacts and Issues Related to Proposed Changes in Oregon’s Interstate Speed Limits” by Monsere et al. (2004). New topics, including impacts of different prevalent strategies in work zones and truck equipment on vehicle speeds and safety were reviewed. The report reviews literature published since 2004 and indexed on databases such as Transport Research International Documentation (TRID), Web of Science, PubMed, Engineering Compendex, and Google Scholar using a list of keywords. Additionally, the reference lists of a number of key sources were mined to identify additional references.
